What You'll Learn
Dr Gundry's diet and cancer prevention
Dr Gundry is an American physician, low-carbohydrate diet author, and former cardiothoracic surgeon. He is the author of several books, including *Dr Gundry's Diet Evolution: Turn Off the Genes That Are Killing You and Your Waistline* and *The Plant Paradox: The Hidden Dangers in 'Healthy' Foods That Cause Disease and Weight Gain*. The latter promotes a controversial and pseudoscientific lectin-free diet.
Gundry's advice focuses on heart health and follows the conventional wisdom of Western diets, including drinking a glass of red wine per day, increasing the intake of plants and nuts, reducing simple carbohydrates, and consuming fish and grass-fed meats. He also recommends a keto version of his diet to starve tumors of sugar, which is their main fuel source.
In *The Plant Paradox*, Gundry claims that lectins, a type of plant protein found in numerous foods, cause inflammation resulting in many modern diseases. He sells supplements that he claims protect against or reverse the supposedly damaging effects of lectins. However, scientists and dietitians have classified Gundry's claims about lectins as pseudoscience, and there is little evidence to support the theory that lectins are as harmful as Gundry proposes. T. Colin Campbell, a biochemist and advocate for plant-based diets, states that *The Plant Paradox* contains numerous unsupported claims. Robert H. Eckel, an endocrinologist and past president of the American Heart Association, argues that Gundry's diet advice contradicts the recommendations of several established health organizations.
Gundry's diet involves a strict lectin-free diet for 3 days, plus a daily regimen of light exercise and drinking at least 8 cups (1.9 liters) of water, tea, or decaf coffee each day. It also emphasizes whole, nutritious sources of protein and fat while banning nightshades, beans, legumes, grains, and most dairy.
While there is criticism of Gundry's theories, some people, especially those with pre-existing digestive problems, respond well to a lectin-free diet.

The Plant Paradox diet
While some people, particularly those with pre-existing digestive issues, may find relief from following a lectin-free diet, there is little evidence to support Gundry's claims about the dangers of lectins. Critics, including scientists and dietitians, have classified his claims as pseudoscience and argued that his advice contradicts established dietary recommendations.
Additionally, while the Plant Paradox Diet is not explicitly designed for weight loss, it may promote increased feelings of fullness due to its emphasis on whole, nutritious sources of protein and healthy fats, while excluding most starchy foods.

Lectins and cancer
Lectins are highly specific proteins that bind to carbohydrates and are found in many plants, animals, and bacteria. They are known to ward off potential predators or pathogens. In plants, lectins are found in beans, quinoa, and tomatoes, among other foods.
In his book, *The Plant Paradox*, Dr. Steven Gundry recommends a lectin-free diet, claiming that lectins cause inflammation, resulting in many modern diseases. He sells supplements that he claims protect against or reverse the effects of lectins. However, scientists and dietitians have classified Gundry's claims about lectins as pseudoscience, and his dietary advice has been criticised by experts, including endocrinologist Robert H. Eckel, who argues that it contradicts mainstream dietary recommendations.
On the other hand, some sources suggest that lectins may have potential benefits in cancer treatment and diagnosis. Wheat germ agglutinin (WGA) was the first lectin shown to agglutinate cancer cells, and other plant lectins, such as mistletoe lectin, have been found to induce apoptosis and autophagy in cancer cells. This suggests that lectins could be developed into anticancer drugs.
While the potential benefits of lectins in cancer treatment are being explored, it is important to note that consuming raw beans, which contain lectins, could be harmful. However, cooking beans may reduce the lectin content and make them safer to consume. Further research and clinical trials are needed to fully understand the role of lectins in cancer treatment and to determine their effectiveness against specific cancer cell lines.

The Keto diet and cancer
The ketogenic diet, popularly known as the keto diet, is a low-carbohydrate diet. It involves eating more fat and protein while cutting out most carbohydrates and sugars. This diet forces the body to burn stored fat, a process called ketosis, which usually begins three to four days after eliminating carbs. While the keto diet can lead to weight loss for most people, it may not be the healthiest way to achieve this, and it is associated with potential side effects and risks.
The keto diet has been rumoured to cure cancer. However, it is important to note that no single food or diet can cure cancer. While some research has shown a link between the keto diet and slowed growth of certain tumours in mice, the evidence for its effectiveness in humans is limited to small trials and anecdotal reports. Some of the strongest reports of its potential benefits come from glioblastoma, a very aggressive form of brain cancer. Additionally, a very low-fat diet has been found to reduce the risk of recurrence for certain types of breast cancer.
The keto diet may work in several ways to help cancer patients. Firstly, it may help prevent weight gain during and after chemotherapy, as extra weight increases the chances of tumour recurrence. Secondly, the keto diet may change the expression of genes, which controls cell behaviour. Finally, by depriving the body of carbohydrates, the keto diet may starve cancer cells of their primary energy source, glucose.
However, there are also potential risks associated with the keto diet for cancer patients. Diets high in fat are linked to heart disease and obesity, and some keto-friendly foods like red meat can increase the risk of certain cancers. Additionally, the body may struggle to break down the high amounts of protein and fat in the keto diet, leading to digestive problems. Furthermore, researchers have not ruled out the possibility that the keto diet may worsen cancer by promoting tumour growth.
In conclusion, while the keto diet may offer potential benefits for some cancer patients, it is not a cure for cancer and may carry risks for certain individuals. It is essential to consult with a doctor or dietitian before starting the keto diet or any other diet to ensure it aligns with your health goals and does not interfere with your cancer treatment.
